Stanley Sykes, the Lowell Observatory handyman and carpenter, built this funky structure to house the 13-inch astrograph.  There are two “floors” to this building – the telescope is up a flight of stairs.  Clyde Tombaugh spent many, many long cold nights here, monitoring the drives and keeping an eye on the weather.   A typical exposure could last a full hour, during which he had to keep his eye on the ocular almost constantly.  If a haze came in, he had to judge when – or whether – to close the shutter to preserve the intergrity of the image. 

Here you can see the cool, very much homemade mechanism that opens the observing slot – those rods that will pull open the flap-thingies.

Stanley Sykes began as a bicycle designer.
